<h2>Auxiliary for Controlling the inner algorithm in a GAMLSS Fitting</h2>


<h3>Description</h3>

<p>
Auxiliary function used for the inner iteration of <code>gamlss</code> algorithm. Typically
only used when calling <code>gamlss</code> function through the option <code>i.control</code>.
</p>


<h3>Usage</h3>

<pre>
glim.control(cc = 0.001, cyc = 50,  glm.trace = FALSE, 
             bf.cyc = 30, bf.tol = 0.001, bf.trace = FALSE, 
             ...)
</pre>


<h3>Arguments</h3>

<table summary="R argblock">
<tr valign="top"><td><code>cc</code></td>
<td>
the convergence criterion for the algorithm</td></tr>
<tr valign="top"><td><code>cyc</code></td>
<td>
the number of cycles of the algorithm</td></tr>
<tr valign="top"><td><code>glm.trace</code></td>
<td>
whether to print at each iteration (TRUE) or not (FALSE) </td></tr>
<tr valign="top"><td><code>bf.cyc</code></td>
<td>
the number of cycles of the backfitting algorithm</td></tr>
<tr valign="top"><td><code>bf.tol</code></td>
<td>
the convergence criterion (tolerance level) for the backfitting algorithm </td></tr>
<tr valign="top"><td><code>bf.trace</code></td>
<td>
whether to print at each iteration (TRUE) or not (FALSE, the default)</td></tr>
<tr valign="top"><td><code>...</code></td>
<td>
for extra arguments</td></tr>
